To better understand the semiochemical detection and reception mechanisms that involved in intra- and interspecific communication, host selection and mating behavior of Echinothrips americanus (Thysanoptera: Thripidae), scanning electron microscopy was used to examine the external morphology, distribution and ultrastructure of the sensilla on antennae and mouthparts. According to serial SEM images, seven types of antennal sensilla in total were observed in both sexes. Sensilla on mouthparts were observed concentrating on the maxillary palps, labial palps, and paraglossa, which is consistent with the previous conclusions. Possible function of the external sensilla is also discussed.

为了更好地了解涉及美洲种chin内和种间通讯，寄主选择和交配行为的信息化学检测和接收机制，使用扫描电子显微镜检查了on上感官的外部形态，分布和超微结构。触角和口器。根据连续的SEM图像，在男女中总共观察到七种触角感官。观察到口器上的感官集中在上颌触诊，唇部触诊和舌下吸收，这与先前的结论一致。还讨论了外部感官的可能功能。
